The Subject

The subject of this paper is the best means of determining freezing points in dilute as well as in concentrated solutions. Two things have to be considered: the proper arrangement of equilibrium in the heterogeneous system, and the proper treatment of the instrument used for measuring temperature.

Thermal Data

Using a Bunsen ice calorimeter the following thermal data were obtained for pure hydrogen peroxide:Specific heat of liquid between0°and25°C …................... 0.632 ± 0. 003 cal. per.gm. per degreeSpecific heat of solid between−20°and −10°C.................. 0.41 ± 0.02 cal. per gm. per degreeLatent heat of fusion at meltingpoint, −0.46°C................... 85.83 ± 0.18 cal. per gm.Latent heat of vaporization at 0°C...... 370.17 ± 0.18 cal. per gm.The freezing points of very concentrated solutions of hydrogen peroxide calculated from these data agree closely with the experimental ones. Preliminary measurements of the heat of decomposition of hydrogen peroxide catalyzed by platinum black were also made at 0° and at various concentrations. The results point to 23.54 ± 0.04 kcal. per mole for the heat of the reaction[Formula: see text]a value slightly higher than those found by previous experimenters.
